AAQ and reb Eliezer; I disagree with the shakla vetaryah here, because the poskim say that outdoor or various other temporary minyonim do not require a mechitzah m’ikar hadin. This is very nogaya when davening in a bais ovel or an airport, or any other place where putting up a mechita isn’t practical. I understand the rov’s reply to have had that in mind, and that it is indeed dependent on an individual’s sensitivity in such a case, not that he was getting involved in the machlokes between rav moshe and the satmar rov regarding the ikkar taam for mechitzah.
That being said, I don’t think it has any bearing on the outlook we should have regarding kashrus of a given shaitel or any other tznius issue
